10 Claims.

This invention relates generally to protectors for covering surfaces which it is desired shall receive no paint when adjacent articles or surfaces are being coated with a pigment either by spraying or brushing. More particularly this invention relates to a painting shield especially adapted for use upon doors, similar articles, or parts of buildings and structures.

Among the objects of the present invention is the provision of a painting shield which when in place will completely protect a door or similar article, so that the same may not be soiled, smeared or spattered with paint or other material when adjacent surfaces or objects are being treated. Another object herein is the provision of a painting shield structure which is readily placed into operative position, requiring a minimum of time, eiort and skill and which is also easily and quickly removed after the painting operation is completed.

Another object herein is the provision of a painting shield which is very simply manufactured requiring a minimum amount of the cheapest materials, so that by reason of the low manufacturing cost thereof, the samemay have widespread distribution and use.

A still further object herein lies in the provision of painting shield devices which may be fabricated in large quantities in single standard sizes and yet which may be readily adapted in use, to ft all normal variations in size of the things which it is intended to protect therewith.

These objects and other incidental ends and `advantages will more fully appear in the progress of this disclosure and as pointed out in the appended claims.

In the ldrawings forming a material part of this disclosure and in which similar reference characters designate corresponding parts throughout the several views:

Fig. 1 is a view in perspective showing a first embodiment of the invention as the same appears at the beginning of the operation of placing the painting shield upon an object such as a door.

Fig. 2 is an elevational View of a irst embodiment of the invention after the same has been `placed upon a door, as the same might be seen from the hinge side of the door. In this view, the door knobs are shown in dot-dash lines and the thickness of the shield is exaggerated for purposes of clarity. The door shown is slightly greater in length than the normal door with which it is intended that the painting shield be used.

Fig. 3 is a View similar to Fig. 2 showing the altered position of the parts when the iirst embodiment of the invention is utilized on a door of a length greater than that of the door shown in Fig. 2.

Fig. 4 is a View similar to 2 and shows the altered position of the parts when the r'st embodiment of the invention is used upon a door shorter `than that of either Figs. 2 or 3. Fig. 4 shows the position which the parts will take when the embodiment illustrated in Fig. l is finally placed upon the door.

Fig. 5 is a plan View of a developed blank from which the first embodiment of the invention is constructed.

Fig. 6 is a front View of the first embodiment of the invention after the same has been folded and secured into its operative position.

Fig. 7 is an end elevational view of Fig. 6.

Fig. 8 is a front elevational view of a second embodiment of the invention.

Fig. 9 is a vertical sectional view of Fig. 8 as seen from the plane 9-9 thereof.

Fig. 10 is a front elevational View of a third embodiment of the invention.

Turning now to the first embodiment of the invention, Figs. l to 7 inclusive, it may be seen that the painting shield indicated generally by numeral 2O comprises a rear wall 2|, a front wall 22, fa top portion 23, a bottom portion 24, a stationary member 25 and a movable member 26.

The material of which the shield is constructed is preferably of a thin, tough paper. However, where the shield 20 is used in connection with painting operations involving the use of paints having solvents which are likely to penetrate ordinary paper, it shall not be deemed to be beyond the scope of the present invention to substitute for the paper mentioned, such materials as sheet cellulose, wax paper, cloth, oilcloth, laminated paper and metal foil or sheet materials impregnated with substances which are especially resistant to penetration by certain painting solvents.

The painting shield 20 is preferably made of a specially shaped-like blank of a single piece of sheet material. The configuration of such a blank is seen in Fig. 5. In the formation of the painting shield 20, the front wall and the rear wall are folded toward each other about the lines 21 which where the sheet material so requires may be scored to facilitate the folding operation. When the inner surfaces of the front wall and the rear wall contact, the stationary member is folded about the lines 28, which may also be scored, so that the inner surface of the member 25 may be attached to the upper portion of the outer surface of the rear wall 2|, and there secured in a suitable manner by means of the gum 29.

The member 23 may now be folded upwardly about and toward the outside of the front wall 22 about the lines 3U which may be scored. The shield will now take on the appearance shown in Figs. 6 and 7. It may be noted at this point that the member 25 is not attached to the outer surface of the front wall 22 by means of the gum 3| at .this time.

The rear wall 2| and the member 25 are provided with rows of perforations 32, 33, 34; while the front wall and the member 25 are provided with rows of perforations 35, 35, 31 respectively, which when the two walls are folded about the lines 21 are adapted to become substantially aligned with each other, that is to say, rows 32, 33 and 34 will become substantially aligned with rows 35, 35 and 31 respectively. The rows of perforations 32 to 31 inclusive, are disposed adjacent the open vertical side of shield 20. Adjacent the lines 21 walls 2| and 22 are provided with short rows of perforations 38 and 39 respectively.

The perforations in each of the said rows are comparatively widely spaced from each other. It will of course be understood that depending upon the tearing qualities of the material of which the shield 20 is fabricated, the spaces between these perforations may be altered.

While rows of perforations are used to facilitate the tearing or rupturing of the material of which the shield is made, it will be of course understood that other methods of weakening the material of which the shield is made along predetermined lines or portions thereof may be utilized as for example scoring which may partially penetrate said material, or chemically weaken the same along predetermined lines.

The assembled shield is utilized as follows. 'I'he shield 20 is put into position upon the door 40, in a position indicated generally in Fig. 1, that is to say, with the open vertical side toward the hinges 4| and 42 of the door. The movablei member 26 is passed forwardly underneath the bottom of the door as seen in that figure. The entire shield is then moved to the right and when the portion of the shield having folded lines 21 is in contact with the outer free vertical side edge of the door, the portions of the walls 2| and 22 adjacent rows of orices 38 and 39 are compressed manually toward the door so that the knobs 43 and 44 force themselves through the openings formed in the walls adjacent the knobs. After the shield is smoothed into place, the member 26 is grasped and the gum 3| is moistened. The member 26 is then brought forwardly and upwardly and secure-d to the front surface of the wall 22. In this position the entire shield is supported by the door itself and by reason of the tightness with which the member 26 may be pulled at the time the same is secured to the wall 22, the entire shield is frictionally engaged by the door 40 thereby avoiding any tendency for the shield to slide out of its normal operating position. Furthermore, by reason of the fact that the knobs 43 and 44 project through the openings formed by the rows of perforations 38 and 39, the Shanks of these knobs prevent any undesirable displacement of the entire shield, that is to say, away from the hinge side of the door.

By reason of the fact that the rows of perforations 38 and 39 extend a considerable distance,

it may be seen that only such portions of these rows may be broken or torn to form openings, and that these openings will be formed in proper position with relation to the knobs.

It may now be seen that by means of the aligned rows of perforations 32, 33, 34 and 35, 36, 31 respectively, it is a relatively simple matter to tear off so much of the shield as would extend beyond the vertical door edge, that is to say, adjacent the hinges. This tearing operation may be performed either before the shield is in place o1' may be done after the shield is in place. While only three vertical aligned rows of perforations are shown in the shields adjacent the open side thereof, it will be of course obvious to those skilled in the art to which the present invention relates that any desirable number of these rows may be utilized so that all reasonable door sizes may be compensated for by means ofI this novel feature of adjustment. Furthermore to facilitate the removal of strips of the shield by means of tearing the same along said rows, suitable designs may be printed upon the surface of the shield indicating the distance of each row of perforations from the closed vertical edge of the shield, that is to say, at the fold line 21', so that the painter having a previous knowledge of the size of the door may know along which line of perforations to tear the shield and thus remove any unnecessary or undesirable portion. thereof.

As is clearly illustrated in Figs. 2, 3, and 4 of the accompanying drawings, the member 2G may be folded upwardly in such a way as to make the shield fit the particular door upon which it is used. Thus in Fig. 4 the door 4U is shown corresponding to that in Fig. l while in Fig. 2 a slightly longer door 35 is shown, and in Fig. 3 a still longer door 43 is shown. In each case, adequate compensation can be made by reason of the novel member 23.

Turning now to the seco-nd embodiment of the invention illustrated in Figs. 8 and 9, it may be seen that the general construction vthereof is similar to the first embodiment with the exception that instead of the gum 3| of the first embodiment, a hooked shaped tab 3| is used, and this tab is formed integrally with the member 26 and a group of vertically aligned slots 41, 43, and 49 allows for adjustment of the member 2G' and to take care of differences in door length. While three slots are shown for vertical adjustment, it is of course obvious that any number of suitable slots may be used. Furthermore, while only one tab 3| is shown, a plurality of such tabs could be formed, upon the upper free edge of the member 26.

Turning now to the third embodiment of the invention illustrated in Fig. l0, a button and string arrangement indicated generally by numeral 3|" is utilized for securing the upper or free edge of the member 26". The string 50 is permanently attached preferably to the button 52 and it is wound about both buttons 5| and 52 to make an attachment as is well known. By reason of the fact that a frictional engagement may be made by the string 5G with the buttons 5| and 52 regardless of a vertical displaced posi-` tion of the upper edge of the member 23", it may thus be seen that the member 26 is capable of vertical adjustment similar to the member 25 of the rst embodiment.

It may now be seen that I have provided a novel painting shield which is very easily and cheaply manufactured, and which by reason of its low cost may find a wide distribution and use among those who are painting various structures who desire to protect doors and door-like objects from the effect of paint. In addition to designations which may be printed upon the shield to indicate the relative position of the various lines of perforations, there may be printed thereupon advertisements or other informative material, and after the operation has been completed in a particular room, these shields by tearing along the top and bottom thereof, may be opened up to form a protective floor covering of a temporary nature which will serve to preserve the iioors from the painting operation. Not only are the illustrated embodiments of the present invention adapted to serve efiicientiy from the point of view of acting as a paint shield but also they may be readily installed upon doors of varying sise and when so installed are simply maintained in position without the necessity of any direct connection with the door such as to mar its surface.

The above description has been made rather detailed for clearness of understanding only= but it is not desired to unnecessarily limit the same and the appended claims should be given as broad an interpretation as possible in view of the prior art.
